Abstract
Abstract This invention relates to a two-channel and four-channel autoselector device for a cartridge-type tape player, that is, to a device which selects and actuates a two-channel circuit or a four-channel circuit in a tape player in response to detection of the type of tape cartridge inserted in the player, as to whether it is the two-channel type or the four-channel type. The player has an auto-selector device which is responsive to the physical characteristic of the cartridge inserted therein to operate a mode selector switch rather than having the cartridge operate the mode selector switch directly.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
249 words
In a cartridge-type tape player for playing and/or recording first and second kinds of cartridges having tapes with different numbers of programs thereon, the number of such programs in each cartridge being indicated by a code portion on the cartridge, the player further including latching means operable to a first portion upon insertion of a cartridge into the player to hold the cartridge in the play position and to a second position to release the cartridge for removal from the player, the improvement including in combination, a mode selector switch having a first position for operating the player to play the first kind of cartridge and being movable to a second position for operating the player to play the second kind of cartridge, means responsive to the coded portion on the first kind of cartridge with the same being inserted into the tape player to maintain said mode selector switch in said first position for playing the cartridge, said means further being responsive to the coded portion on the second kind of cartridge with the same being inserted into the player to move said mode selector switch to said second position for playing the second kind of cartridge, and linkage means being responsive to the latching means being operated to the second position to release the cartridge to operate said mode selector switch to said first position, whereby with no cartridge in the player said mode selector switch is always set to play the cartridge of the first type.

In a cartridge-type tape player for playing and/or recording first and second kinds of cartridges having tapes with different numbers of programs thereon, the number of such programs in each cartridge being indicated by a code portion on the cartridge, the player further including latching means operable to a first portion upon insertion of a cartridge into the player to hold the cartridge in the play position and to a second position to release the cartridge for removal from the player, the improvement including in combination, a mode selector switch having a first position for operating the player to play the first kind of cartridge and being movable to a second position for operating the player to play the second kind of cartridge, means responsive to the coded portion on the first kind of cartridge with the same being inserted into the tape player to maintain said mode selector switch in said first position for playing the cartridge, said means further being responsive to the coded portion on the second kind of cartridge with the same being inserted into the player to move said mode selector switch to said second position for playing the second kind of cartridge, and linkage means being responsive to the latching means being operated to the second position to release the cartridge to operate said mode selector switch to said first position, whereby with no cartridge in the player said mode selector switch is always set to play the cartridge of the first type.
Claim 3
Dependent Claim
130 words
The cartridge-type tape player of claim 1 wherein said mode selector switch includes a spring loaded operating rod and locking means locking said rod against said spring pressure to set said mode selector switch in said first position, the player further including cam means coupled to said locking means, said cam means being responsive to the coded portion of the first kind of cartridge being inserted into the player to maintain said mode selector switch in said first position for playing the first kind of cartridge, said cam means further being responsive to the coded portion of the second kind of cartridge to operate said locking means to release said spring loaded rod to operate said mode selector switch to said second position for playing the second kind of cartridge.
Claim 4
Dependent Claim
80 words
The cartridge-type tape player of claim 2 wherein said linkage means includes an arm connected to the latching means and with the latching means being operated to the second position to release the cartridge with the second kind of cartridge being in the player, said arm engages said operating rod and moves the same against said spring pressure until said locking means locks said operating rod against said spring pressure to set said mode selector switch in said first position.
Claim 5
Dependent Claim
146 words
The cartridge-type tape player of claim 1 wherein said mode selector switch includes a spring loaded operating rod and locking means locking said rod against said spring pressure to set said mode selector switch in said first position for playing the first kind of cartridge, the player further including a solenoid having an armature coupled to said locking means, and switch means being responsive to the coded portion of the first kind of cartridge being inserted into the player to maintain said mode selector switch in said first position for playing the first kind of cartridge, said switch means further being responsive to the coded portion of the second kind of cartridge to energize said solenoid whereby said armature operates said locking means to release said spring loaded rod to operate said mode selector switch to said second position for playing the second kind of cartridge.
Claim 6
Dependent Claim
80 words
The cartridge-type tape player of claim 4 wherein said linkage means includes an arm connected to the latching means, and with the latching means being operating to the second position to release the cartridge with the second kind of cartridge being in the player said arm engages said operating rod and moves the same against said spring pressure until said locking means locks said operating rod against said spring pressure to set said mode selector switch in said first position.
Claim 7
Dependent Claim
36 words
The cartridge-type tape player of claim 4 wherein said mode selector switch acts to deenergize said solenoid with said mode selector switch being operated to said second position by the release of said spring loaded rod.
