Abstract
Abstract A taximeter assembly including an electronic calculating module with data memory, an operating keyboard, as well as a data indicating device, consists of two flat housing panels which are joined by detent devices and which are secured together by a lead-sealable screw connection. An electronic taximeter circuit wired on a single printed circuit board is installed between the housing panels and feed-in of all electrical transmitter lines and supply lines is effected, as desired, from the rear or from below, wherein the latter are guided directly to connectors on the printed circuit board. The rear wall of the rear housing panel is constructed, at the same time, as a mounting plate for installation in a vehicle. A compact, extremely flat taximeter device having its circuitry in a single printed circuit board system enables arrangement of the device in an optimal installation position within or on the outside of the dashboard of a vehicle.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
149 words
In a taximeter assembly including electronic calculating means having data storage capacity, an operating keyboard and data indicating means for displaying actual operating data and stored data upon request, the improvement comprising: housing means consisting essentially of a front and a rear flat housing panel; detent means interlocking said front and rear panels together; lead-sealed screw connection means securing said front and rear panels together; electronic taximeter circuit means mounted on a single printed circuit board installed between said front and rear housing panels; actuating elements and an exchangeable face plate having operating indicia thereon mounted on said front housing panel; said rear housing panel being arranged to serve as a carrier element receiving said electronic taximeter circuit means and being equipped with means for feeding cable connections therethrough, said rear housing panel simultaneously operating as the mounting plate for said assembly for fastening said assembly in a vehicle.
Claim 2
Dependent Claim
149 words

Claim 3
Dependent Claim
29 words
An assembly according to claim 1, wherein said means for feeding cable connections through said rear housing panel are arranged to feed said cable connections from the rear thereof.
Claim 4
Dependent Claim
28 words
An assembly according to claim 1, wherein said means for feeding cable connections through said rear housing panel are arranged to feed said cable connections from below thereof.
Claim 5
Dependent Claim
57 words
An assembly according to claim 1, wherein said detent means consist of resilient locking arms which are formed as a unitary piece with said front housing panel from elastomer plastic material, said arms having locking projections which engage in cutout portions provided in said rear housing panel when said front and rear housing panels are connected together.
Claim 6
Dependent Claim
59 words
An assembly according to claim 1, further comprising screw fastening means for securing said front and rear housing panels together, said screw fastening means comprising at least one fastening screw which is insertable from the front of said assembly for connecting said front housing panel with said rear panel, said fastening screw being adapted to be sealed with lead.
Claim 7
Dependent Claim
40 words
An assembly according to claim 3, wherein said front and rear housing panels are formed with rabbets to form therebetween a rabbeted joint structured so that an overlapping connection results between said housing panels when said panels are joined together.
Claim 8
Dependent Claim
34 words
An assembly according to claim 1, wherein said single printed circuit board having said electronic taximeter circuit means mounted thereon is constructed to serve simultaneously as a carrier plate for said data indicating means.
Claim 9
Dependent Claim
28 words
An assembly according to claim 1, further comprising transmitter lines and supply lines guided into the interior of said assembly directly to connectors on said printed circuit board.
Claim 10
Dependent Claim
48 words
An assembly according to claim 1, further comprising downward and rearward predetermined breakout zones provided in one of said housing panels, said predetermined breakout zones being adapted to be broken away to enable a downward and rearward guidance of electrical transmitter lines and supply lines for said assembly.
Claim 11
Dependent Claim
67 words
An assembly according to claim 1, wherein said rear housing panel is formed with a rear wall constructed as a mounting plate for enabling fastening of said assembly in a vehicle, said rear wall having small protuberances which reinforce said rear wall and which comprise formed blind end bores through which the assembly may be fastened from the inside thereof onto an installation surface by self-tapping screws.
Claim 12
Dependent Claim
102 words
An assembly according to claim 1, further comprising a programming release and test switch on said printed circuit board, an opening defined in said front housing panel through which access may be provided for actuating said programming release and test switch, a lead-sealable fastening screw and a cover plate for securing said front panel, said front and rear housing panels being connected and secured together by means including connections of all internal electrical supply lines and transmitter lines as well as fastening means for mounting said assembly on a vehicle, said lead-sealable fastening screw operating to secure said assembly against external tampering.
