Abstract

Abstract An automatic cartridge playing system which has a start-switch means, a selective switch means for selecting in advance a predetermined cartridge, and a tape end detecting means for detecting the end of a magnetic tape. The device also has a rotary switch group, a rotary switch rotating means for rotating the rotary switch group by any of the start-switch means, and a selective switch means or tape end detecting means. The device further has holding means for holding one or more cartridges operative by the first rotary switch of the rotary switch group, a magnetic head held in reproduceable state by the second rotary switch of the selective switch means and rotary switch group, and reproducing means for amplifying the output of the magnetic head and for increasing the volume of its output. Thus, the automatic cartridge playing system of this invention may selectively and automatically play any cartridge or cartridges in preset order.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 255 words
An automatic cartridge reproducing system for a tape recorder comprising: a. start switch means; b. selective switch means for selecting from a plurality of magnetic tape cartridges those cartridges which are to be reproduced by said tape recorder; c. tape and detecting means for determining the end of the magnetic tape in said cartridges; d. a rotary switch device comprising a plurality of rotary switch means; e. a first rotary switch means of said plurality of rotary switch means, connected to said selective switch means, for sequentially connecting each switch of said selective switch means; f. holding means, coupled to a second rotary switch means of said plurality of rotary switch means, for maintaining each of the selected ones of said plurality of magnetic tape cartridges in a reproduce state during the reproduction of the magnetic tape; g. magnetic head means for reproducing the magnetic tapes; h. a third rotary switch means of said plurality of rotary switch means, coupled to Said magnetic head means, for holding said magnetic head means in a reproduce state corresponding to the selected ones of said plurality of magnetic tape cartridges; and i. rotary switch rotating means, coupled to said start switch means, said selective switch means, and said tape end detecting means, for rotating said plurality of rotary switch means in response to the actuation of said start switch means, said selective switch means and said tape end detecting means, whereby upon actuation of said start switch means said system automatically sequentially reproduces each selected magnetic tape cartridge.
Claim 2
Dependent Claim 255 words
An automatic cartridge reproducing system for a tape recorder comprising: a. start switch means; b. selective switch means for selecting from a plurality of magnetic tape cartridges those cartridges which are to be reproduced by said tape recorder; c. tape and detecting means for determining the end of the magnetic tape in said cartridges; d. a rotary switch device comprising a plurality of rotary switch means; e. a first rotary switch means of said plurality of rotary switch means, connected to said selective switch means, for sequentially connecting each switch of said selective switch means; f. holding means, coupled to a second rotary switch means of said plurality of rotary switch means, for maintaining each of the selected ones of said plurality of magnetic tape cartridges in a reproduce state during the reproduction of the magnetic tape; g. magnetic head means for reproducing the magnetic tapes; h. a third rotary switch means of said plurality of rotary switch means, coupled to Said magnetic head means, for holding said magnetic head means in a reproduce state corresponding to the selected ones of said plurality of magnetic tape cartridges; and i. rotary switch rotating means, coupled to said start switch means, said selective switch means, and said tape end detecting means, for rotating said plurality of rotary switch means in response to the actuation of said start switch means, said selective switch means and said tape end detecting means, whereby upon actuation of said start switch means said system automatically sequentially reproduces each selected magnetic tape cartridge.
Claim 3
Dependent Claim 71 words
