Description

  This invention is used when observing the surface contamination or surface deformation of the object to be measured and recording the observation date, or when comparing the current date with the visual recognition of the expiry date written in fine characters attached to foodstuffs etc. The present invention also relates to a magnifying glass with a calendar that can easily perform these operations.

  Surface contamination of the object to be measured, adhesion of dust, and even fine surface deformation cause the quality of the measurement value to deteriorate. For example, in order to enable precise length measurement, the standard scale for scale calibration has a precise memory attached to a rectangular parallelepiped glass, but when actually calibrating the scale using this standard scale, If a small amount of dust adheres to the standard scale, incorrect calibration may occur due to misreading of the scale. For this reason, it is indispensable to inspect with a magnifying glass whether dust or the like adheres to the scale portion on the standard scale surface.

  Such a standard surface inspection is carried out periodically to some extent, but it is preferable for the standard scale management to record the date and time when the surface inspection was actually performed. Therefore, it is necessary to record the date and time of the examination at the end of the examination, but in many cases the wristwatch can tell the time when the examination was conducted, but there are few people who have a wristwatch that shows this today. Often there is no clear memory, and there is often no calendar around the place. For this reason, a date that is not sufficiently confirmed may be described, and at that time, proper management of the standard scale is not performed.

  In addition, when selling food, it is obliged to display the date of manufacture, the expiration date, and the expiration date according to the type of food. Therefore, consumers are careful not to purchase items that are as fresh as possible after confirming these items, or that have expired or expired. However, these date descriptions are often recorded small, and it is often difficult for the elderly to see even with reading glasses. Therefore, if you really want to check this, you need to look at them with a magnifying glass. In that case, even if the expiration date can be confirmed with a magnifier, it is often impossible to remember how many days it was today when there is no calendar around. There is also a problem that makes judgment difficult.

A portable timepiece with a magnifying glass in which the cover glass of the portable timepiece can be used as a magnifier is described in the following patent document.
JP-A-8-152486

  As described above, a magnifying glass is indispensable for regularly checking whether dust or the like is attached to the surface of the standard scale, for example, for standard scale management, and records the date and time when the inspection was performed. There is a problem that it is particularly difficult to check the date, although it is necessary. In addition, since the expiration date, etc. described for food management is small, it is difficult for the elderly, etc. to visually recognize it, and it is necessary to use a magnifying glass. There was a problem that even if I was able to confirm, I couldn't remember how many days it was today.

  Furthermore, the technique disclosed in the above-mentioned patent document uses a loupe as the cover glass of a portable watch in order to eliminate the difficulty of carrying the magnifying glass on a regular basis, and this portable watch is often a wristwatch. Therefore, when using a magnifying glass with this wrist watch on the wrist, it is difficult to use it because it is difficult to use it, and it is difficult to remove the wrist watch when using it. . Moreover, it is not appropriate to use the simple magnifier fixed to such a wristwatch for the standard scale management as described above because of its performance.

  Therefore, a main object of the present invention is to provide a magnifying glass with a calendar that can easily check the date and time in an environment where the magnifying glass is used.
