Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to a cassette-type tape player that is compact and lightweight, making it convenient to carry.

BACKGROUND TECHNOLOGY AND PROBLEMS A cassette-type tape player is used to record and play back audio signals, etc., or only to play back, using a normal compact cassette tape. The tape cassette is composed of a main component containing the main parts thereof and a sub-component supported so as to be slidable to be pulled out or pushed into the main component.When a tape cassette is attached, the sub-component is is pulled out to form a storage space for the tape cassette, and when the tape cassette is not attached, the sub-components are pushed in to reduce the external dimensions, making it compact and convenient to carry. has been done.

FIGS. 3 and 4 show a cassette-type tape player having such a telescoping outer case together with a tape cassette attached thereto, in which the outer case 1 has a main body side portion 1a and a lid side portion 1b. The main body side portion 1a is formed of a main component 2 and a sub-component 3, and the sub-component 3 is supported by the main component 2 so as to be able to slide in the direction of arrow a. . A chassis 4 on which a tape cassette TC is placed is attached to the main component 2, and main components such as a drive mechanism for the cassette tape, a recording and reproducing circuit, etc. are built below the chassis 4. Also, on the chassis 4, there is a fourth
Tape cassette placed as shown in the figure
Two reel shaft members 5 protrude to engage tape reels built into the TC. Also,
An operation panel section 6 is provided on the outer surface of the main component 2 and includes a plurality of push-in operation buttons for selecting, switching, and canceling operation modes. On the other hand, the lid side portion 1b of the exterior casing 1 is attached to the sub-component portion 3 via the hinge portion 8.
It is configured to be opened and closed with respect to the main body side portion 1a.

In the cassette type tape player constructed in this way, when the tape cassette TC is not installed, the sub-component part 3 is pushed toward the main component part 2 and moves to the position shown by the dotted line in FIG. The dimension of the outer case 1 in the direction of the arrow a, that is, the depth dimension, is reduced to the same extent as the depth dimension of the tape cassette TC, for example.
When the tape cassette TC is attached, the sub-component part 3 is pulled out from the main part 2 to take the state shown by the solid line in FIG. side part 1
A tape cassette accommodating part 9 is formed on the chassis 4 in the tape cassette TC, and a tape cassette TC is mounted on the tape cassette accommodating part 9, and the reel shaft member 5 engages with a tape reel built in the tape cassette TC.

In this way, when the tape cassette TC is not attached, the depth dimension of the outer case 1 is reduced and the overall external dimension is further reduced.
Although it is considered extremely convenient to carry, such a cassette type tape player has the following problems. That is, when the tape cassette TC is attached and the operation buttons on the operation panel section 6 are operated to switch or cancel the operation mode, the operator usually holds the entire tape cassette TC with one hand and uses his or her thumb to perform the operation. The selected one of the buttons is hooked, and the remaining fingers touch the sub-component part 3 of the main body part 1a and the lid part 1.
b, and the selected operation button is pushed in with the thumb. Therefore, at this time, the sub-component portion 3 of the main body side portion 1a is pushed in the direction of being pushed into the main component portion 2 side of the main body side portion 1a together with the lid side portion 1b, and the lid side portion 1b is restricted in position by its inner surface coming into contact with the side surface of the tape cassette TC, but since the inner side of the sub-component section 3 is a space, the main component section 2 can be moved with the hinge section 8 fixed. There is a risk that the sub-component part 3 may be distorted by being deformed and moved as if being pushed to the side, and the operator may feel uneasy about the response.

Purpose of the Invention In view of the above, the present invention provides an outer casing having a main component housing a main component such as a drive mechanism for the cassette tape, and a sub-component supported so as to be slidable relative to the main component. When the sub-component is pulled out from the main component and the tape cassette is attached, the sub-component is pushed in the direction of the main component. It is an object of the present invention to provide a cassette-type tape player in which deformation and movement of sub-components is significantly reduced.

Summary of the invention A cassette-type tape player according to the invention is comprised of a main component that incorporates a drive mechanism for the cassette tape, and a sub-component that is supported so as to be able to slide on the main component. The tape cassette is provided with an exterior casing that forms a tape cassette accommodating part within the main and sub-components in a state in which the tape cassette is pulled out from the main component, and a detection means is provided for detecting attachment of a tape cassette to the tape cassette accommodating part. Thus, when the tape cassette is mounted in the tape cassette storage section, the detection means prevents the sub-component from sliding in the direction of being pushed toward the main component.

With this configuration, when the tape cassette is installed, the movement of the sub-component in the direction of being pushed into the main component is restricted, so for example, when the operation button is operated, the sub-component is Even if the sub-component is pressed in a direction toward the main component, the deformation and movement of the sub-component will be extremely small.

Example Examples of the present invention will be described below.

1 and 2 show essential parts of an example of a cassette-type tape player according to the present invention. This example is
For parts other than the main parts shown in Figs. 1 and 2, such as the overall appearance and the structure that enables the reduction and expansion of the outer casing, the cassette type shown in Figs. 3 and 4 described above is used. The configuration is similar to that of a tape player, and redundant explanation thereof will be omitted. Further, in FIGS. 1 and 2, parts corresponding to those shown in FIGS. 3 and 4 are designated by the same reference numerals as in FIGS. 3 and 4.

FIG. 1 is a perspective view showing the inside of the part corresponding to the part surrounded by the broken line X in FIG. FIG. 3 is a schematic cross-sectional view of the same portion in an enlarged state of the casing.

In the examples shown in FIGS. 1 and 2, a guide plate member 10 is provided inside the side surface portion of the sub-component portion 3 of the main body side portion 1a constituting the exterior casing 1, where the hinge portion 8 is provided. It is attached by screwing or the like and moves together with the sub-component 3. The guide plate member 10 is disposed between a pin 11 fixed to the inside of the side surface of the main component 2 of the main body side portion 1a and the bottom surface of the main component 2, and has a tip at its tip. An engaging protrusion 12 is provided that engages with the pin 11 and serves to prevent the sub-component 3 from being pulled out beyond a predetermined amount from the main component 2. Therefore, when the sub-component section 3 is pulled out from the main section 2 or pushed into the main section 2 side, the bottom surface of the sub-component section 3 and the guide plate member 10 are connected as shown in FIG. holds the bottom surface of the main component 2, and the pin 11 and the bottom surface of the main component 2 grip the guide plate member 10, so the sub component 3 is held in a stable posture in the direction of the arrow a. , can slide in a straight line.

A detection lever member 13 having an L-shape as a whole is rotatably supported on the guide plate member 10 via a shaft 14 . Detection lever member 13
One arm portion 13a extends in the direction along the guide plate member 10 with a length shorter than that of the guide plate member 10,
Similar to the guide plate member 10, the pin 11 and the main component 2
and the other arm portion 13b.
extends upward, and a plate-shaped detection portion 15 is provided at its tip, which is pressed by the side surface of the tape cassette when the tape cassette is attached. This detection lever member 13 is always biased by a spring 16 in a counterclockwise direction about the axis 14 in FIG. It is designed to take.

Note that the configuration including the guide plate member 10 and the detection lever member 13 is provided not only at one corner of the sub-component 3 but also at the other corner opposite thereto.

Based on the above-described configuration, as shown in FIG. 2, the sub-component part 3 is pulled out from the main component part 2,
When the engaging protrusion 12 provided on the guide plate member 10 is brought into engagement with the pin 11, the tape cassette TC can be accommodated on the chassis 4 disposed within the main component 2. A housing portion 9 is formed. As mentioned above, the main components such as the drive mechanism for the cassette tape are built in the lower part of the chassis 4. In this state,
Since the arm portion 13a of the detection lever member 13 is shorter than the guide plate member 10, the arm portion 13a is shorter than the guide plate member 10.
3a is released from being held between the pin 11 and the bottom surface of the main component 2, and rotates clockwise around the shaft 14 in FIG. 2 without being restricted by the pin 11. It is supposed to be obtained.

When the tape cassette TC is installed in the tape cassette accommodating section 9 in this state, the detection lever member 1 is moved as shown by the dashed line in FIG.
The detection unit 15 provided in the tape cassette
Pressed by the side part of the TC, thereby
The detection lever member 13 rotates about the shaft 14 against the biasing force of the spring 16, and assumes a position as shown by the dashed line in FIG. As a result, the arm portion 1 of the detection lever member 13
The tip end of 3a comes into contact with the pin 11 extending from the main component 2.

Therefore, when the tape cassette TC is installed in the tape cassette storage section 9, even if a force is applied to the sub-component section 3 in the direction of pushing it toward the main component section 2, the arm section 13a of the detection lever member 13 The tip of the pin 11 contacts the pin 11 to restrict the position of the sub-component 3, and prevents the sub-component 3 from moving in the direction of being pushed toward the main component 2. That is, at this time,
This prevents the sub-component 3 from deforming or moving.

In this state, when the tape cassette TC is removed from the tape cassette storage section 9,
The detection lever member 13 is rotated counterclockwise about the shaft 14 in FIG. 2 by the biasing force of the spring 16, and is returned to the original position shown by the solid line in FIG. Therefore, when the tape cassette is not attached, the sub-component part 3 can be pushed toward the main component part 2, and the dimension of the outer casing 1 in the direction of arrow a, that is, in the depth direction, can be reduced. .

In the above example, the detection lever member 13 is attached to the sub-component part 3 of the main body side part 1a constituting the outer case 1, and the pin 11 is fixed to the main part 2 of the main body side part 1a. Instead of this configuration, a configuration may be adopted in which a detection means corresponding to the detection lever member 13 is attached to the main component 2 of the main body side portion 1a, and a member equivalent to the pin 11 is fixed to the sub component 3 of the main body side portion 1a. It may be taken.

Effects of the Invention As is clear from the above explanation, the cassette-type tape player according to the present invention has a structure in which the outer case can slide into the main component housing the main components such as the drive mechanism for the cassette tape. By pushing the sub-component toward the main component, the external dimensions when the tape cassette is not attached can be reduced compared to when the tape cassette is attached. In addition, when the sub-component is pulled out from the main component and a tape cassette is attached, this is detected by the detection means, and the sub-component is moved toward the main component. Since the position is regulated to prevent movement in the pushing direction, even when a force is applied to the sub-component in the direction of pushing it toward the main component, the deformation and movement of the sub-component can be significantly reduced. As a result, it is possible to avoid distortion of the sub-components, and the user does not feel uneasy about the response when operating the operation button.
