Figures 8 to 12 show a second embodiment of the present invention, which is a tape recorder that allows playback via earphones in addition to recording. Figure 8 is a plan view showing the external appearance of the case. Figure 9 Therefore, Fig. 12 is a plan view showing the operation of the Heradreno <-. O The difference from Fig. 1 is that an earphone terminal TO has been added, so when an earphone (not shown) is connected, it goes into playback mode. It is as it should be. The structure is almost the same as that shown in FIG. 1, but the difference is that the erasing head 22 is separated from the head lever 24 on which the recording/reproducing head 73 is mounted. In FIG. 9, the erasing head 22 is placed on the erasing head lever T1, and the erasing head lever 71 is connected to the recording operation section 71 extending outward from the case 1.
α, a guide groove 71b that engages with the pin 17 implanted in the base plate 14 for sliding and rotation, and a positioning pin 71C that regulates the stop position, which engages with the pin 72 implanted in the base plate 14. The recess 71 d'? :Has. The head lever 24 is provided with a positioning recess 24C via a spring portion 24b'ft. Next, the effect will be explained. FIG. 9 shows the tape recorder in a stopped state, and the recording operation section 71α is pushed 11 toward the case 1.

In the soldered state, the crown □2 is in the pushed-in position. The positioning pin 71C is removed from the head/lever positioning recess 24C, and at the same time, the recess 71d engages with the pin 72 to maintain the stopped state. The head lever 24 is also positioned on the flywheel lever drive shaft 12e and is separated from the cassette 5. Fig. 10 shows the playback state with the crown 2 pulled out to the 2'' position with the recording operation part 71α pushed in, and the head lever 24 is connected to the flywheel L//<12 head lever drive shaft 12eV.
The recording/playback head 73'Y cassette 5 is rotated clockwise from the stopped state shown in FIG. 9 through the guide groove 24α from C.
bring it into contact with. Since the position of the erase head lever 71 is regulated by the pin 72, the erase head 22 remains stopped. FIG. 11 shows the state when entering the recording state, with the crown 2 in the pushed-in position 2' and the recording operation section 71α pulled out.

By pulling out the recording operation part 71α, the erasing head lever T1 moves and the recessed part 71d is disengaged from the pin 72, and at the same time, the positioning pin 71C bends the spring part 24h of the head lever 24 and engages with the four positioning parts 24C. do. Therefore, the erasing head lever 71 moves almost integrally with the head lever 24, although there is some play in clockwise rotation.

FIG. 12 shows the recording state, in which the crown 2 is pulled out one step while the recording operation section 71α is pulled out. As the head lever drive shaft 12g moves, the head lever 24 rotates clockwise through the guide groove 24α from the state shown in FIG. The erasing head 22 is also pressed against the cassette 5 by turning the erasing head lever 71 via the pin 71 C'lt. After that, repeat the push operation of the start/stop button 3, and repeat recording and stopping. FIG. 13 shows the head lever 2 according to the third embodiment of the present invention.
It is a four-turn plan view. This is almost the same as the second embodiment, but this time the recording operation member 81α is pushed in to enter the recording state, and pulled out for use in the playback state. The recording operation lever 81 has an engaging protrusion 8.1g, a positioning guide groove 81b, and a stop layer 81? ' has.

One side B1d of the guide groove 81b has springiness.

To describe the operation, when the operating portion B1 (L) is pushed into the push-in position as shown by the solid line in FIG.
It operates together with the lever 24, and the recording state and release state are repeated by operating the crown 2 in and out. Next, when the recording operation section 81α is brought into the state shown by the two-dot chain line in FIG.
The retaining convex portion 81g comes into contact with the pin 82 implanted in the head lever 24 and becomes free from the concave m82α of the head lever 24.

When the crown 2 is moved in and out, only the head lever 24 swings, repeating the regeneration state and release state.

FIG. 14 shows a fourth embodiment of the present invention, in which manual rewinding and fast forwarding of the tape 190 in the first embodiment are eliminated, and the motor T is used to perform the rewinding and fast forwarding. In this case, when the crown 2 is pushed in and the flywheel lever 29 is at the neutral position, the flywheel barrel 11 is in the neutral position.
α is not in contact with either the winding wheel 13 or the supply wheel 16. When the crown 2 is pulled out one step, the flywheel lever 29 rotates clockwise via the mandarin duck 27.
The flywheel cylindrical portion 11W comes into contact with the winding wheel 13 and is in a state where rotation can be transmitted, and by operating the start/stop button 3, recording, playback, or fast forwarding is performed by increasing the motor speed by 70 revolutions. Next, when the crown 2 is pulled out two steps, the flywheel lever 29 rotates counterclockwise via the mandrel 27, and the flywheel cylindrical portion 1112 comes into contact with the supply wheel 16, allowing rotation to be transmitted. Switch the terminals so that the direction of rotation is reversed. If you repeatedly press the button 3 to start/stop, the tape 19 will run backwards and stop repeatedly.As a modification of the first embodiment, when recording, it is recommended to use a new tape or a tape that has been erased by another machine. As a premise, if the erasing head is omitted and only the recording head is used, the process will be further simplified. Of course, if the recording head is used as a recording/playback head, recording and playback become possible.

As described above, according to the present invention, the operating members of a tape recorder are arranged in a manner similar to operating the crown of a watch, thereby reducing the number of operating members and simplifying the operating motion, and reducing the amount of movement of the winding stem by a small number. The blocks for the supply car, take-up car, and cassette were placed in the center, and the block for the battery and motor, the block for the time display board, and the block for the microphone. The case is divided into three parts, and the cassette block, motor, battery, microphone, and time display plate are arranged without overlapping each other, and the flywheel is controlled by a swinging lever placed between the main plate and the back cover. The motor is supported by the base plate and the belt pulley is moved to the back cover side, allowing manual fast forwarding and rewinding of the tape, reducing power consumption. The erasing head and the recording head were fixed to one lever and moved, the erasing head was omitted because the tape was used for recording, and the display part could be used in combination with a clock. It can also be used for tape recorders, and in conjunction with this, tape recorders can also be used as clocks.

The internal structure is simple and ultra-compact, allowing for arbitrary recording and playback in conjunction with the clock's time function, and easy replay of Alano's messages on a tape recorder in conjunction with the clock's alarm function. Therefore, it is possible to achieve a tape recorder that is thin and convenient as a portable device that can be used as a notebook.
