Abstract

PURPOSE:To ensure the storage of recorded medium and correct recording by providing an accidental recording prevention member used in common as mis-storage prevention member to a main body for recording the information. CONSTITUTION:A mis-recording prevention notch 6a is provided to a part of a memory card 6 of picture information, a cap 6c covering it selectively is provided and when mis-recording prevention by th cap 6c is desired, the card loading is prevented by the cap 6c. That is, the cap 6c is slided upward to engage the recessed part 6e' and the projection 6d, then the mis-recording prevention notch 6a is covered, the cap 6c is in contact with a storage exit 5 when the loading is applied from the storage inlet 5 into the camera main body 1, the loading is disabled and the recording is blocked. Thus, mis-recording and duplicate recording are prevented, accidental erasure is prevented and since the loading is noticed before the recording, the chance of recording is not missed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a storage medium used as a means for recording information such as image information in electronic still cameras and the like.

[Prior Art] Electronic still cameras that record still images on magnetic sheets have been in practical use for some time, but magnetic sheets cannot fully demonstrate their properties under harsh environments with temperature and humidity conditions.
They are also susceptible to vibrations and shocks, so electronic still cameras that record images on semiconductor memory have recently been proposed instead of magnetic sheets.

This is a device in which a predetermined number of still images are recorded on a removable semiconductor memory, for example, in the form of a card, and then reproduced.

[Problems to be Solved by the Invention] Double recording will occur unless some kind of means is provided to prevent double recording or erroneous erasure in the image information memory cart made of the semiconductor storage medium as described above.

There was a problem in that the data could be erased incorrectly, resulting in incorrect recording or preservation of the recorded material.

This problem was developed in order to solve this problem, and the purpose is to provide a storage medium suitable for electronic still cameras and the like that ensures accurate recording and preservation.

[Means for Solving the Problems] In order to achieve the above object, the storage medium of the present invention is provided with an erroneous recording prevention member that also serves as a member to prevent erroneous storage in the main body.

[Sakukawa: By having the above configuration, it is possible to prevent erroneous recording and double recording, and also to prevent erroneous erasure, and it is not necessary to realize that the erroneous erasure prevention state is in effect only when attempting to record. , you can notice it when loading, so you don't miss a chance to record.

Figure 1 is a perspective view of an electronic still camera and a memory card which is a semiconductor storage medium according to a first embodiment of the present invention, and Figures 2 and 3 are top sectional views of Figure 1. be.

To explain the first embodiment with reference to FIGS. 1, 2, and 3, l is the camera body, 2 is a release button, 3 is a finder, 4 is a lens, and 5 is a semiconductor provided in the camera body. This is a storage opening for a memory card, which is a storage medium. Further, 6 is a memory cart, 6a is a notch for preventing erroneous recording of this memory card 6, 6b is a contact for transmitting the signal of the memory card 6, 6C is a slide cap, 6d is a protrusion, 6e,
6e' is a recessed portion. Further, 7 is a notch detection contact for preventing erroneous recording, and 8 is a communication contact with the contact 6b of the memory cart.

Now, slide the cap 6c downward in the figure to make the recess 6
When the projection 6d is engaged with the protrusion 6d, the erroneous recording prevention notch 6a is exposed, and when the camera body 1 is stored from the storage opening 5 as shown in FIG. 2, the erroneous recording prevention notch detection contact 7 is turned ON and the memory cart contact 6b and the communication contact 8 are connected to perform normal recording, but when the cap 6C is slid upward to engage the four parts Be' and the protrusion 6d as shown in FIG. 1, the erroneous recording prevention notch 6a is covered. There is a storage opening 5 inside the camera body 1.
When attempting to store it from the storage port 5, the cap 6C hits the storage opening 5, making loading impossible and preventing recording.

As described above, in the first embodiment of the present invention, a notch 6a for preventing erroneous recording is provided in a part of the memory card 6 for image information, and a cap is selectively provided to cover the notch 6a, and this cap prevents erroneous recording. If an attempt is made to do so, the cap is configured to prevent card loading.

3 is a perspective view showing the electronic still camera shown in FIG. 1 and a memory cart which is another embodiment of the present invention, and FIGS. 4 and 5 respectively show the memory card shown in FIG. It is a perspective view when set to a prevention state and an erroneous storage prevention state.

Next, the embodiments shown in FIGS. 3, 4, and 5 will be explained. Reference numeral 11 denotes a memory card, which is a semiconductor storage medium;
A is a communication contact of this memory card 11, and 12 is a slide lever provided on the memory card 11 so as to slide along the elongated holes 12a and 12b.

Now, with the slide lever 12 in the state shown in FIG. 3, that is, with the slide lever 12 positioned downward, the memory card 11 is inserted into the camera body l through the storage opening 5, and normal recording is performed. On the other hand, when the slide lever 12 is moved to the center position as shown in FIG.
Among the communication contacts 11a, the read/write signal contact 11
Since the camera is shielded, it is impossible to record even if it is stored in the camera body 1.

Furthermore, when the slide lever 12 is moved to the center position as shown in FIG. 5, the protrusion 12d of the slide lever 12 protrudes from the memory card 11, making it impossible to insert it through the storage opening 5 of the camera body 1. , therefore, reproduction can also be prohibited.

As described above, in the embodiments shown in FIGS. 3, 4, and 5, the image information memory card 11 is connected to the communication contact 11.
Focusing on the fact that it is connected to the camera body l through a, among the communication contacts 11a provided on the memory cart 11, the signal contact for the REIT/LEI l- signal is covered with the slide lever 12 to prevent erroneous recording. It is made to be stored away.

The slide lever 12 is used not only to prevent erroneous recording but also to prevent the memory cart 11 from being stored in the camera body l.

In addition, 1st. In both the second embodiment, when the cart is loaded into the regenerator, the cart storage opening is widened so that the cart can be stored. In addition, the notch 6a for preventing erroneous recording
Accidental erasure can be prevented even if the camera is set to recording mode when the camera is opened or closed.

[Effects of the Invention] As described above, according to the present invention, it is possible to prevent erroneous recording when using a storage medium in a recording device such as an electronic still camera by providing a loading prevention function at the time of loading. You will now be able to do this and never miss a chance to record. When loading this medium into a recording/reproducing machine, the storage opening may be made wide so that the loading prevention function does not work, but the accidental erasure prevention function can also be obtained in this case.
