Multipurpose calculator

A multipurpose calculator includes a casing having one pair of side slots made at the front on both side walls for pivotally movable connection thereto of a movable cassette block, said movable cassette block being applicable to move within 180.degree., four elongated holes made on the front end wall through the body of the casing for setting therein of a scraper, a fluorescent marker, a flat type screw driver, and a cross type screw driver respectively. The movable cassette block comprises an illuminating apparatus to provide a solar power calculator with sufficient energy for operation. The said casing includes a rectangular recess for setting thereon of a solar calculator, a cutter and a steel tape respectively mounted on both sides for specific application. According to above-described arrangement, a calculator is practical for multipurpose application.

BACKGROUND OF THE INVENTION 
The present invention is to provide a multipurpose calculator equipped with 
steel tape, cutter, illuminating apparatus, fluorescent marker, screw 
driver, and scraper. 
Regular solar power operated calculators are exclusively designed for 
calculation, without having any supplementary illuminating apparatus. 
Conventional calculators with self-provided illuminating apparatus are 
relatively heavy, not convenient to carry. Further, few calculators of 
regular portable type are designed to carry with any self-provided 
illuminating apparatus. 
SUMMARY OF THE INVENTION 
The present invention is related to a multipurpose calculator with 
self-provided steel tape, cutter, illuminating apparatus, fluorescent 
marker, driver, and scraper, and more particularly to a calculator adapted 
for multipurpose application. According to the present invention, a 
multipurpose calculator is comprised of a casing, a solar calculator, and 
a movable cassette block. Said casing includes two side slots respectively 
arranged at the front end on both side walls for pivotal connection 
thereto and of said movable cassette block for form a complete working 
box. There is provided a rectangular recess made on the top surface of 
said casing for setting thereon of a solar calculator. Said casing also 
comprises a cutter and a steel tape respectively arranged on both lateral 
sides. There are four elongated holes made on the front end wall of 
through the body of said casing for receiving scraper, fluorescent marker, 
flat type screw driver and cross type screw driver respectively. The 
movable cassette block comprises thereinside an illuminating apparatus to 
provide sufficient illumination and to provide the solar calculator with 
sufficient energy for operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
According to the present invention, a multipurpose calculator is comprised 
of a casing, a movable cassette block, an illuminating apparatus, a 
cutter, a pusher plate, a steel tape, one set of tools, and a clip. 
FIG. 1 illustrates the outer appearance of a multipurpose calculator 
constructed according to the present invenion. As shown in FIG. 1, the 
casing 1 includes one pair of slots 14 bilaterally disposed at upper end, 
for respectively setting therein of the two linking rods 13 of a movable 
cassette block 12, such that said movable cassette block 12 is flexibly 
attached to the casing 1 for making pivotal movement within an angle of 
180.degree.. Said movable cassette block 12 includes a double 
swinging-doors-switch 3. Said double swinging-doors-switch 3 may be drawn 
backward to support said movable cassette block 12 when said movable 
cassette block 12 is slantly disposed. Said movable cassette block 12 also 
includes thereinside an illuminating apparatus comprised of dry battery 
cells 11, bulbs 16, and mirror 15, wherein said battery cells 11 is 
controlled by said swinging-doors-switch 3 to turn on said bulbs 16 to 
illuminate. The illumination provided by said bulbs 16 is reflected by 
said mirror 15 onto the solar energy collector 26 of a calculator disposed 
on said casing 1 such that said solar power operated calculator is 
functioning efficiently and free from interference of outer lighting 
condition. 
Referring to FIG. 3, there is provided a steel tape 9 winding round a post 
8 arranged in said casing 1 on the right side. The operation of said steel 
tape 9 is similar to regular measuring tape. When it is used in dark 
place, the said illuminating apparatus may be operated to provide 
illumination to help the application. 
Referring to FIG. 4, there is provided a cutter in said casing 1 arranged 
on the left side, along the elongated slide slot 4, wherein a pusher plate 
5 is connected with a cutting blade 7 by a screw 6 to control the sliding 
of the cutter. By means of said arrangement, a calculator is designed to 
provide a snap-off cutter. 
Referring to FIG. 6, when said cassette block 12 is lifted to a vertical 
position, four elongated holes 17 are presented on the end wall of said 
casing 1. Said four elongated holes 17 are arranged for setting therein of 
a scraper 23, a fluorescent marker 18, a flat type screw driver 20, and a 
cross type screw driver 21 respectively. By means of said arrangement, a 
calculator is designed to provide one set of tools for multipurpose 
application. 
Referring to FIG. 7, there is provided a resilient clip 24 on the back side 
of the said casing 1, such that the whole assembly of the apparatus may be 
attached to one's belt for ready use. 
As indicated, the structure herein may be variously embodied. Recognizing 
various modifications will be apparent, the scope hereof shall be deemed 
to be defined by the claims as set forth below.
