JPH03230385A - Cassette case with sound recording function - Google Patents

Abstract

PURPOSE:To simplify an operation by housing such a tape cassette that a nonrecorded tape is wound around a supply hub in order to bring a take-up hub under the beginning state of winding the tape into a cassette case incorporated with a sound recording head and a microphone, etc. CONSTITUTION:First of all, at the time of recording a sound, when a switch lever 25 of the cassette cases 13 and 14 is moved downward, a protrusion between claws of the supply hub 3 is withdrawn by a tape stopper 25d to allow the hub 3 to turn freely, so that a switch 26 is turned on. A motor 9 is rotated and the tape 15 is fed by a capstan 5 and a pinch roller 8, and then an input of the microphone 11 is recorded by the recording head 21 via an amplifier 30 into the tape 15. When the lever 25 is moved upward on recognition of the completion of winding the tape 15 with an LED 32 turned off, a stop mode is effective. When the sound recording is wanted to be further continued, a case lid 14 is taken off, and a U-shaped part 20d of a sliding plate 20 is pushed to the right, so that the roller 8 and the head 21 are moved to the right, and the cassette 1 can be taken up by hand. When the cassette 1 is reversely set, the recording is carried out on the other side.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention is based on the recording 8! This relates to a cassette case that incorporates functions.

(Prior Art) Conventionally, a cassette case was simply a case for storing a tape cassette. Therefore, when you want to record on the tape cassette, you always have a tape recorder ready, take the tape cassette out of the case, insert it into the tape recorder, and then perform the recording operation.

(Problem to be solved by the invention) This had the following problems.

(1) If you went out without a tape recorder and suddenly wanted to record something, you had to buy an expensive tape recorder in addition to a tape cassette. If the person already has it, it will be a wasted purchase.

(2) Recordings from meetings and seminars are rarely played back on the spot, but often after returning to the home or i-place. In this case, radio cassette tape recorders, headphone players, etc. There is always a need for a compact de-recorder that only has a recording function and is extremely cheap, since the clarity is better when played back using several units.

The present invention has been made to solve the above problems.

(Problems and Means for Solving the Problems) The present invention provides at least one recording throat, a microphone,
A capstan, a pinch roller, a drive shaft that engages with the take-up hub, a motor, an amplifier, a power supply for the motor and amplifier, and a power switch component are built into the set case. A tape cassette containing an unrecorded tape wound in the supply hub is housed so as to be in the initial state.

(Function) If you turn on the power switch of the cassette case configured as above, recording will start immediately. When recording on one side is finished, turn the power switch to 0FFL, open the cassette case lid, and insert the tape cassette. If you flip the cassette over, close the cassette case again, and turn on the power switch, recording of the opposite side (side 8) will start.

When playing back, use a radio, recorder, headphone player, etc. at home or at work.

(Example) Examples of the present invention will be described below.

FIG. 1 and FIG. 8 show an embodiment of the present invention.

Figure 1 is a plan view with the cassette case lid removed.

FIG. 2 is a right side view taken along the line A-B in FIG. 1, and 13 is a cassette case lid, and 14 is a cassette case lid.

Furthermore, in FIGS. 1 and 2, reference numeral 15 denotes a non-recording tape, which is fully wound around the supply hub 3 of the cassette 1.
i (15a), and the cassette 1 is set in a fixed position by the positioning pin 6.7 and the push spring 4n.

Figure 3 shows the state in Figure 1 with the cassette 1 removed, 16 is a drive shaft that engages with the winding hub 2, 17 is a drive shaft pulley, 18 is a belt, 19 is a flywheel, and 20 is a recording A sliding plate equipped with a head 21 and a pinch roller 8 is guided by guide pins 4b and 4c that are integrated with the chassis 4, and springs 20a and 20b that are integrated with the sliding plate 20 are repelled by spring hooks 4d and 4e that are integrated with the chassis. As a result, the pinch roller 8 has a habit of always moving to the left on the paper.
This is the contact pressure to the capstan 5. The recording position of the head 7 door 21 is determined by the contact position of the pinch roller 8 and the capstan 5. A head holder 22 is fixed to the sliding plate 20 with screws 23.

24 is an azimuth adjustment screw, and 20c is a tape guide. 25 is a switch lever whose center of rotation is a shaft 4f that is integrated with the chassis 4, and a spring 25a that is integrated with the switch lever 25.

It pinches and stops rattling.

FIG. 7 shows a cross section 0-P-QR in FIG. 3, and 4p is a click hole at the OFF position of the switch lever 24.

FIG. 8 shows an electric circuit, in which 3o is an amplifier, 31 is a motor servo amplifier, and 32 is a recording display LED which is turned on during recording or whose lighting brightness changes according to the recording level. As already mentioned, 9 is the motor, 10 is the battery, 11 is the microphone,
21 is a recording head, and 26 is a switch.

Next, the operation will be explained.

First, when I try to record, the cassette case 13.1
If you tear off the film (not shown) on the outer packaging of No. 4 and move the switch lever 25 downward in No. 1, the tape-fastened No. 2
5d, the protrusion between the claws of the supply hub 3 retreats, and the hub 3 becomes able to rotate freely, and the switch 26 is turned on. The motor 9 rotates and the chi 115 is sent at a constant speed by the capstan 5 and the pinch roller 8, and the input from the microphone 11 is recorded on the tape 15 by the recording head 21 via the amplifier 30.

When the user knows visually that the tape 15 has finished winding or by turning off the LED 32, the switch lever 25 is moved upward in FIG. 1 to enter the stop mode. If you want to continue recording, remove the cassette case holder 14 and press the U-shaped part 20dp of the sliding plate 20.
If you push the cassette to the right in FIG. 1, the pinch roller 8 and recording head 21 will move to the right, and the cassette 1 can be lifted by hand. If cassette 1 is set upside down, recording on the opposite side (8 sides) will be performed in the above procedure.

To playback, take out only cassette 1 as described above and listen to it with good sound quality using a radio cassette recorder, phono player, etc. at home or at work.

In principle, recording using a cassette case with this recording function uses one cassette, and to reduce costs, for example, lead wires are spot welded directly to batteries without using contacts. It also uses a lot of molded parts and also has a spring effect.

Figures 9 to 12 show another embodiment, which is an invention in which the sliding lever 20 of the previous embodiment is abolished to reduce costs.

FIG. 9 shows a plan view corresponding to FIG. 1, and 4o is a head holding member that holds the pinch roller 41 and is integrated with a pinch roller arm 42 having a spring action;
0 shows a 5-TU-V-W-X sectional view of FIG. 9, and FIG. 11 shows a perspective view of the head holding member 40. The head holding member 40 has a U-shaped cross section and a lower wall. A recording head 43 is attached to the section 40a. A tape guide 40c protrudes from the end of the back wall 40b, and a pinch roller arm 42 is integrally formed therein. 40d is the head holding part 4
This is the earthen wall section of 0. The upper and lower walls 40a40d are the cassette 1

4a, 44b (FIG. 12) and is pressed by a cassette pushing spring 44n to hold the cassette 1 at the reference position.

FIG. 12 shows a state in which the cassette 1 is removed from FIG. 9, and is clearly simplified compared to FIG. 3.

The rest of the structure is the same as the embodiment in FIGS. 9 to 12, and will therefore be omitted.

Next, to explain the operation, the difference from the embodiment shown in Figures 9 to 12 is that the recording of one side is completed, and the
If the operator does not have the cassette to play, remove the cassette 1 and place the head holding member 40 on the cassette 1.
Remove it from the cassette, turn it around, and attach it to the cassette 1 again so that the opposite side of the cassette 16 (side 8 is up) is installed.

The azimuth adjustment of the head can be done by attaching the head holding member 40 to a cassette with a test tape installed in the same manufacturing loft, and setting the azimuth of the head holding member 40 alone to 5Jq in advance. 9 is a plan view showing an example in which the invention shown in FIG. 9 and FIG. 12 is applied to a microcassette 5o. Since it is essentially the same as FIG. 9 and FIG. 12, the explanation is omitted. do.

Incidentally, it is not surprising that the invention shown in Fig. 1 and Fig. 8 can also be applied to micro cassettes.

(Effect of the invention) As described above, the present invention has the following effects.

(1) When you want to record on the go, you can just buy a cassette in a ``cassette case with recording function'' while you are out, and there is no need to take your tape recorder with you every time you go out.

(2) Even if you forget your tape recorder and go out, there is no need to buy an expensive tape recorder.

(3) Since it only has a recording function, it is extremely easy to operate, and even children and the elderly can record without fail.
