Description

[Detailed Description of the Invention] The present invention relates to a small electronic computer and a tape recorder with a radio, more specifically, a small electronic computer formed in the shape of a triangular prism and a tape recorder with a radio.

In recent years, electronic computers, radios, tape recorders, etc. have all become smaller and more portable.

And these are becoming essential items for businessmen.

However, carrying these items separately is very cumbersome.
It's inconvenient.

It would be very convenient if these could be integrated into a compact device.

However, even if these are configured as a compact unit, it is usually placed on a desktop, where it is most often used, so that each device can perform its functions in the optimum condition and operate in the optimum condition. Otherwise, it will not be practical.

The purpose of this invention is to meet the above requirements by housing an electronic computer, a radio, and a tape recorder in a small triangular prism-shaped housing, and by sharing common parts between the three. It has been made compact by cleverly combining the components, and when used on a desktop, it is extremely convenient, allowing each device to perform its functions in the optimum condition and operate in the optimum condition. Our goal is to provide practical electronic computers and tape recorders with radios.

Hereinafter, the present invention will be explained based on the illustrated embodiments.

FIG. 1 is a perspective view showing an embodiment of the electronic computer and tape recorder with radio of the present invention, in which Aij shows the surface where the numeric keys and numerical display window are arranged, and B shows the window of the tape cassette loading chamber. , as viewed from the left with the side where the radio tuning dial window is placed facing forward.

In Figure A, on the front inclined surface 1a of the tape recorder 1, there are four parts provided on the left side of the front inclined surface 1a to prevent the computer's head from protruding above the inclined surface 1a. 2a
The computer's numerical display window 3 is located in the center right corner, and the computer's main switch knob 4 is located below it.
are arranged respectively.

Further, on the right side of the ridge at the upper end of the inclined surface 1a, a group of operation buttons 5 for operating the tape recorder 1 such as recording, playback, and stop are arranged. On the right end surface 1d of the tuning dial knob 6, a radio/tape recorder switching knob 1 and a volume control knob 8 (see figure B) for common use with the radio and tape recorder are provided.

In Figure B, the front inclined surface 1b of the tape recorder 1, which was the rear side in Figure A, has a window 9 for the tape cassette loading chamber on the left side and a radio tuning dial window 10 on the upper right side. , a speaker window 11 for common use with the radio and tape recorder is provided below, and a built-in microphone window 12 for the tape recorder is provided at the center of the right end.

In addition, a built-in antenna, a power source battery (not shown), and the like are appropriately housed within the housing.

The electric circuit on the electronic computer and radio tape recorder of the present invention constructed in this way is constructed as shown in FIG.

That is, the electric circuit of the tape recorder is composed of a well-known microphone 111, a recording/reproducing magnetic head 112, an erasing head 113, amplifiers 104 and 105, a speaker 106, a motor M, and the like.

As is well known, operations such as recording, playback, and erasing are performed by operating the main switch S2 and changeover switches 85 to S8, respectively.

Power supply battery 109Ff: , Main switch S for computer through AC adapter connection jack 110
It is commonly used via the main switch S3 for the radio and the main switch S2 of the cheap 1% coder.

As is well known, the electric circuit of the attached radio tuner consists of an antenna 108 and a tuner circuit 107, and the output of the tuner circuit 107 can be increased by connecting it to the input terminal of the amplifier 1050 for the tape recorder using a changeover switch S4. and the output end of the amplifier 105 is connected to the selector switch S5.
It is configured to be connected to the input end of the speaker 1060.

The main switch s3 that operates in conjunction with the changeover switch S4 is composed of a double switch, and the switch S4 is connected to the fixed contact S.
When the switch is switched to the 4b side, the main switch S3 is switched to the fixed contact 53a)S3b side in conjunction with this,
Each tuner circuit 107 is connected to the amplifier circuit of the amplifier 105.

Furthermore, by operating the recording/playback button of the tape recorder, the main switch S2 of the tape recorder is turned on, and radio recording becomes possible.

Also, if you open the main switch S3 of the radio,
Since only the main switch S2 of the tape recorder is turned on, recording with a microphone or reproduction with a tape is performed.

The electrical circuit in FIG. 2 shows the radio in operation.

The circuit of the attached electronic computer includes a well-known arithmetic element section '101. which uses a power supply battery 109 in common with the tape recorder and is connected via a main switch S1. It is comprised of a numeric key 102 for adding input signals, a numeric display section 103 for output operation, and the like.

In the tape recorder 1 constructed as described above, depending on the purpose of use, the switches 81 to S8 are operated by the husband's operating members, i.e., the main switch knob 4 of a computer, the radio, the switch knob 7 of a tape recorder, recording, and playback. By operating the operation button group 5, etc., a desired electric circuit is constructed and a desired operation is performed.

As is clear from the above description, according to the present invention, a computer operating member and a radio/tape recorder member are separated on both inclined surfaces of the triangular prism-shaped housing, and when facing each side, each It can be used and operated as an independent device, and there is no fear of erroneous operation.

In addition, by optimizing the inclined surface, each device can fully demonstrate its functions, and its operability can also be optimized.

Furthermore, by adopting a triangular prism-shaped casing, it has good stability when used on a desk or the like, and can also be used as a substitute for cross-linking, bringing about remarkable effects not seen before.
