Abstract

PURPOSE:To prevent a careless operation in the middle of loading and unloading a cassette magazine by positioning the operational button of the 1st main body at an operable place when the 2nd main body comes to a standby position and setting said button inoperable at a separate place. CONSTITUTION:The 1st main body 1 has a variety of operational buttons 9, and the 2nd main body 2 has a through hole 10 at a position opposite to said buttons 9. The 2nd main body 2 is made slidable in a stroke range where the operational buttons 9 installed on the 1st main body 1 can be visible or invisible according as the 2nd main body 2 changes its attitude between the 1st and 2nd states. Namely, the 2nd main body 2 moves so as to reduce with respect to the 1st main body 1. The operational buttons 9 installed on the 1st main body 1 protrude from the through hole 10 installed on the 2nd main body 12 when a pinch roller is brought into a standby position on a capstan spindle, and the operational buttons 9 become operable. On the other hand, when the pinch roller is separated from the capstan spindle, the operational buttons 9 become inoperable.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a small and lightweight cassette tape recorder.

2 Page Conventional Technology In recent years, cassette tape recorders have become noticeably smaller and lighter. A tape recorder that partially protrudes from the tape recorder body is known. In such a configuration, portability with the cassette magazine attached is impaired.

Therefore, one measure to reduce the size of the cassette magazine when it is installed and to improve its portability is to have a first body that has a reel stand and a capstan shaft, a magnetic head and a pinch roller that slides onto the first body. a second body that is rotatably held; and a cassette lid that is rotatably held on the first body, and the second body is slidable from the first body when a cassette magazine is attached or not attached. When the cassette magazine is installed or removed, the second main body slides from the first main body to a position where the cassette magazine can be installed or removed. It is conceivable to change the form so that it is in the second state.

Problems to be Solved by the Invention However, as mentioned above, the configuration changes between the state in which the cassette magazine is attached or not, and the state in which the cassette magazine is attached or detached, and the attachment of the cassette magazine is difficult. Recording and playback of the cassette tape recorder itself during installation or removal.

If the various operation buttons, such as fast forwarding and rewinding, are operable, you may end up operating the operation buttons before the cassette magazine has been fully loaded or unloaded. This has the problem of causing inconvenience.

Means for Solving the Problems In order to solve the above problems, the cassette tape recorder of the present invention has a first main body having a reel stand and a capstan shaft, a first main body having a magnetic head and a pinch roller, and a second main body having a magnetic head and a pinch roller.
a second body slidably held on the body of the first body;
a cassette lid rotatably held in the main body, and provided on the first main body when the second main body is brought to a ready position where the pinch roller is pressed against the capstan shaft. The operation button is made to appear in an operable position and is configured to slide within a stroke range that renders the operation button inoperable when the pinch roller is at a distance from the capstan shaft. This is a feature.

Effect of the present invention With the above-described configuration, when the second body is in the first state in which it does not slide from the first body, the pinch roller is brought to the ready position where the pinch roller is pressed against the jap stan shaft, The cassette magazine is either attached or not attached, and in this state, the operation button provided on the first body protrudes from the second body and becomes operable. On the other hand, when the second body slides from the first body to a position where the cassette magazine can be attached or detached, the pinch roller is separated from the capstan shaft, and the state is such that the pinch roller is separated from the capstan shaft and the cassette magazine is allowed to be attached or detached. In this state, the operation button provided on the first body is retracted into the second body.

It becomes impossible to operate. As a result, it is possible to eliminate the inconvenience caused by not being able to operate the operation button when the cassette magazine is attached or detached, and operating the operation button due to unnecessary sounds.

The first main body 1 includes a reel 6, a capstan shaft (not shown), and capstan bearings (not shown) that rotatably support the capstan shaft at both ends of the tape running section of the cassette magazine. do. Also, the second
The main body 2 is equipped with a magnetic head (not shown) and holds a pinch roller (not shown) so as to be freely movable. 1, the second main body 2 has a locking member 6, the first main body 1 has a locking pin 7 with which the locking member 6 is engaged, and the cassette lid 3 has a locking member 6. It has a lock release knob 8 for releasing the engagement state with the lock pin. The lock member 6
When the second body 2 is contracted relative to the first body 1 and brought to the ready position where the pinch roller is pressed against the capstan shaft, the lock pin 7 and When engaged, the cassette magazine stored in the cassette lid is held in an attached state in which it is fitted onto the reel 6. In this state, by operating the lock release knob 8, the engagement state of the lock member 6 with the lock pin 7 is released, and the first body 1 shifts to extend the second body 2. and cassette lid 3.
Allows for rotation.

The first body 1 has various operation buttons 9 for recording, playback, fast forwarding and rewinding, and the second body 2 has the operation buttons 9.
7, having a through hole 1o at a position facing the .

I'm here. The second main body 2 is configured to be slidable within a stroke range such that the operation button 9 provided on the first main body 1 appears and disappears as the form changes between the first state and the second state. There is. In the state in which the second body 2 is moved to shrink with respect to the first body 1 and brought to the ready position where the pinch roller is pressed against the capstan shaft, The operation button 9 provided on the first body 1 protrudes from the through hole 1o provided on the second body 2, and the operation button e itself can be operated. On the other hand, when the second body 2 is extended from the first body 1 and brought to a position where the pinch roller is separated from the capstan shaft, the second body 2 is moved to the first body 1. The provided operating button 9 is retracted into the through hole 10 provided in the second main body 2, and the operating button 9 itself becomes unoperable.

Next, the installation and removal of the cassette magazine with the above configuration will be explained. First, when a cassette magazine is to be mounted, the cassette magazine is mounted by shifting from the first state to the second state and rotating the cassette lid 3. and,
The loading of the cassette magazine is completed by closing the cassette lid 3 to the second state and then moving to the first state.
