Abstract
Abstract A cassette tape recorder includes operating buttons for controlling the functions of the tape recorder, a cassette ejection button for exposing a cassette accommodating section having a cover, and an arresting member interlocked with the operating buttons and ejection buttons. The arresting member selectively hinders the operation of the ejection button when any of the operating buttons is pushed to put the tape recorder in a tape running mode and the operation of the operating buttons when the cassette accommodating section is exposed, thereby providing a foolproof mechanism for the cassette tape recorder.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
238 words
A cassette tape recorder comprising: a cassette accommodating section having a movable cover and receiving a cassette therein; p1 a plurality of operating members arranged parallel with each other in a row and movably in a substantially same direction between operative and inoperative positions for controlling functions of said tape recorder; frame means for movably supporting said plurality of operating members; cassette ejection means capable of being actuated for opening said cover to expose said cassette accommodating section for insertion and extraction of the cassette; and stopping means comprising a unitary member supported on said frame means to extend in a direction substantially perpindicular to said operating members in said row and coupled to said ejection means, said stopping means being movable in a direction crossing the moving direction of said operating members to selectively occupy, when said ejection means is not actuated, a first position where said stopping means is locked by at least one of said operating members which extends into the moving path of said stopping means in the operative position thereof so as to inhibit the actuation of said ejection means and, when said ejection means is actuated, a second position where said stopping means is located in the moving path of said at least one operating member when all of said operating members are in the inoperative positions so as to inhibit the movement of said one operating member to the operative position.
Claim 2
Dependent Claim
238 words
A cassette tape recorder comprising: a cassette accommodating section having a movable cover and receiving a cassette therein; p1 a plurality of operating members arranged parallel with each other in a row and movably in a substantially same direction between operative and inoperative positions for controlling functions of said tape recorder; frame means for movably supporting said plurality of operating members; cassette ejection means capable of being actuated for opening said cover to expose said cassette accommodating section for insertion and extraction of the cassette; and stopping means comprising a unitary member supported on said frame means to extend in a direction substantially perpindicular to said operating members in said row and coupled to said ejection means, said stopping means being movable in a direction crossing the moving direction of said operating members to selectively occupy, when said ejection means is not actuated, a first position where said stopping means is locked by at least one of said operating members which extends into the moving path of said stopping means in the operative position thereof so as to inhibit the actuation of said ejection means and, when said ejection means is actuated, a second position where said stopping means is located in the moving path of said at least one operating member when all of said operating members are in the inoperative positions so as to inhibit the movement of said one operating member to the operative position.
Claim 3
Dependent Claim
86 words
A cassette tape recorder as claimed in claim 1, in which said stopping means comprises a bar-shaped stopping member having slots corresponding to end portions of respective said operating members, the operating members being slidably supported in said frame, said stopping member being slidably arranged in a direction perpendicular to the sliding direction of said operating members and being locked at said first position by inserting at least one of the end portions of said operating members into the corresponding slot provided in said stopping member.
Claim 4
Dependent Claim
175 words
A cassette tape recorder as claimed in claim 1, in which said ejection means has an ejection lever and another operating piece which is turned through a predetermined angle in a predetermined direction upon operation of said ejection lever, and said stopping member is biased in a predetermined direction by a spring to abut against said another operating piece, said stopping member being so designed that said members stops said operating piece to turn in the predetermined direction under the condition that said stopping member is at said first position and is locked in a place by said operating members, said stopping member allows said another operating piece to turn in the predetermined direction under the condition that said stopping member is at said first position but is not locked in place by said operating members, and said stopping member is moved toward said second position from said first position against the force of said spring by being depressed by said another operating piece when said another operating piece is turned in the predetermined direction.
Claim 5
Dependent Claim
121 words
A cassette tape recorder as claimed in claim 3, in which said ejection means comprises a roller which can be engaged with and also disengaged from an engaging section provided in an arm constituting a part of an opening and closing mechanism of said cover, said roller being biased in a predetermined direction by a spring to abut against said arm, and in which upon closure of said cover said roller is caused to roll along said arm to engage said engaging section thereby to lock said cover in a closed state, and upon operation of said ejection lever said roller is moved in a predetermined direction to disengage from said engaging section thereby to release the locking of said cover.
Claim 6
Dependent Claim
97 words
A cassette tape recorder as claimed in claim 1, comprising a switching mechanism, said switching mechanism comprising a first member operating in association with the opening and closing operation of said cover and a second member operating in association with the operation of said first member, said stopping means comprising a stopping member and said stopping member being biased in a predetermined direction by a spring to abut against said operating member, said stopping member being placed into said second position from said first position by being depressed by said second member when said cover is opened.
